-
A platinized glassy carbon electrode (GCE), electropolymerized with 1,2-diaminobenzene and immobilized with glucose oxidase(GODx), is used in the construction of a sensor for the determination of glucose. The platinum coating provides an increased current response to the oxidation of bydrogen peroxide as compared with a bare GCE. The permselectivity of 1,2-diaminobenzene polymer can drastically reduce the effects of electroactive interferents, such as aseorbie acid and uric acid, and prevent high molecular weight species from fouling on the electrode surface. The sensor remains the advantages of conventional GODx electrode such as high response, wide linear range, fast response and has high selectivity and reproducibilty.
